They say one man's trash is another man's treasure, and this certainly seems to be the case for Chilean artist Rodrigo Alonso.

Alonso is the mastermind behind the geeky chairs pictured above. They're made from pieces of old tech donated by Chilean recycling company Recycla.

The graphic designer creates the stools by pouring epoxy resin into a mold filled with the e-waste; the legs are made from cast aluminum. Alonso produces the chairs in limited editions, but he also takes special orders. Since no set of e-waste is alike, each piece is original and dyes can also be added to the resin to add color.

For Alonso, the project is more than just a piece of furniture or work of art. The chairs, which are called N+ew for No More Electronic Waste, is also about recycling e-waste. Though consumer electronics companies are slowly becoming more eco-conscious and more recycling programs are being put in place, the amount of e-waste is still expected to rise exponentially by 2020, especially in developing countries.
